To all whom t may concern:

Be it known that l, Vieron C. Rniirnnne, a 4citizen of the UnitedStates, residing` geina, inthe county 'of rice andv State oitl/Visconsin, have invented a: new anduseful Combination Door Lo'clr, oi"`Which the following is a specification.

The device forming` the subject' inatter oi this application isa lock,and the iiif vention aims to provide novel means Where` by the bolt ofthe lock may` be controlled through the instrumentality or. alperiii'uta'- tion mechanism. Another object of the inventionl is toprovide novel means whereby the bolt oit the lock may be manipulatedfrom the inside oie the door` even though the bolt may be held againstmovement troni the outside of the door. 'lt is Within the province ofthe disclosure to improve generally and to enhance the utility ofdevices oir' that type to which the invention appertains.

l/Vith the above and other objects in view,

which will appear' as the descriptionpro ceeds, the invention, residesin the combination and arrangement of parts and in the details scribedand claimed, it being` luiiderstornl that, Within the scope of what isclaimed, changes in the precise embodiment of the invention shown canbe' made without de-` partingv from the spirit of the invention.

.overhanging the tongue 37 holds the tongue for `tiexu're, under theaction of the finger 36. A detent 41 is mounted pivotally at 42 on theplate 4 and has a shoulder 43 adapted to cooperate with the notch 31 inthe arni 16. The.detent 41 has a linger 45 which projects' beyondtheshoulder43. The

back plate 7 carries a bearing -46 wherein atubular` shaft 47F'isfjournaled, the shaft having an arni 48, operating behind the detent41 and' adapted to cooperate with the `finger in a way which will be setforth hereinafter. A compression `spring 49 "cooperateswith the frame 6and with Vthe detent 41 to swing the detent upwardly until the detentabuts ,against the tubular shaft 47, as shown in Figure 3. A spindle 56is'journaled and held for rotation in the plate 11 and casries rvanouter turning head 51, the spindle being held` removably, but againstrotation, in a rectangular opening 52 in the shaft 47. leg stop 53projects from the plate 4 and is adapted to be engaged by the arni' 4Slon the shaft 47, when they guideway 64 `formed in the plate 4. On itsouter surface, the plate 4 is supplied with a rib 59.` There is a slot56 in the rib 59. 41 stud 57 projects from the head 101 and is movablein the slot 58. At its outer end, the stud 57 is supplied with the aknob 60.

i A foot `piece 61 is disposed between the knob' 60 and the rib 59 andis slidable in a superiicial` slot 62 formed in the rib, the.

foot piece being carried by the stud 57. The slide rod 551s suppliedwith projections 65. j

Perinutation tuinblers 66 are located be tween the flanges 54 and arejournaled on 'the slide rod 55. rllhe tumblers 66 are maintained inaxial alinernent, not only by the slide rod 55, but, as well, by'interen'gaging annular ribs and grooves 67 on the abutting faces of thetuinblers. The tumblers 66 have l recesses 68 wherein the projections 65on the slide rod are received when the tuinblers are rotated. rlhetuinblers 66 have trans- `verse slots 69. 'll/'hen the slots 69 arealined,

the projections on the slide rod 55' may inove through the slots, itbeing possible, thus, Vfor the rod 55 tohave longitudinal movement. Thetace plate 4 has an opening 70 through which the tumblers 66 areexposed. There is a iiange 71 on the plate 4 at one end of the opening70,`the flange carrying an index `72 adapted to cooperate withcharacters `on the tumblers 66. A retaining bar 74 is secured at 75 tothe inner surface of the plate 4 and holds the spring brakes 76 adaptedto bear on the periphery of the tuniblers66. n

Let it' be supposed that selected ones of the characters 73 on thetuinblers 66 have been lined up'with the index 72 so that the slots 69in the tuinblers are alined, the slide rod 55 having been moved to theright- (Figure 3),until the yprojections 65 are located in the recesses68, motion being imparted to the slide rod through the instrumentalityoi' the knob v60 on thestud 57. The projection 56 on the slide rod 55has been moved so far to the right that the spring 49. has raised thedetent 41 until the shoulder on the detent is out of the vpath olf theupper end oi the arm 16.V When the knob 14 is rotated, thev cross pin 2Oin the neck 17 cit 'the knob being received in the seat 19 ci* the hub18 of the arrn`16 imparts swinging movement to the arm 16,` the arin 16retracting the locking bolt 64, `the spring 37 serving te `return thelocking bolt to the position shown in Figure '3, when the knob 14 isreleased. VVihen the knob 27 is turned, the sleeve 22 is rotated, andswinging movenient is imparted to the'arin 16, since the sleeve 22 isintegral with the hub 16 ot the arm. The bolt 34 in view of theforegoing inay be retracted troineither side or the door. 'i

Y Suppose, however that it is desired to loclt the bolt 34 vin advancedposition. Then, the slide rod 55 is moved to the lett (Figure 3) landthe tuinblers 65 are rotated, the tuinblers cooperating with theprojections 65 on the sliderod -55 to hold the slide rod in the positionto which it may have been advanced, toward the le'lt (Figure 3). l/Vhenthe slide rod 55 is moved to the left, the projection 56 on the sliderod engages the detent 41 and swings the: Ad'etent 41 downwardly, theshoulder 43 on the detent engaging the arrn 16, within the notch 81, andthe spring 49 being compressed. The

yarni` 16 cannoty now swing counter-clockwiseligure 3) and the' bolt64is held in advanced position, inr engagement with the keeper lB'on thejarnb 2. When it is desired to set the locking boltv 34 tree, theproperV combination isset up by alining certain ofthe characters 73 onthe tuinblers 66 with the index 72, the slots 69 vin the tumblers thenbeing alined, to receive the lprojections 65 on the slide rod 55,whereupon the slide rod may be moved to the right, into the positionshownfin Figure 3, the Spring 49 swinging the detent 41 upwardly, andsetting the arin 16 free, so that :ee-eenen e 3 downwardljyxy until theshoulder 13 on the d tent is engaged with the uppe.` end oi the arni 1G,the erm 16 thus being held ui rinse swinging movement and it beinginipos sible to retract the bolt 34: by either of the vblers 66, andrelease the slide rod because the tumblers are accessible 'troni theouter side of the door only. ln order to nctuate A und retract the bolt34, under the conditions above specified, the knob 2? ispulledoutwardly, the arni 16 moving to the" right (Figure G) along withthe lrnob 27, because the sleeve 28 of the knob is connected at to thesleeve 22 on the hub 18 of the arin V 16. lWhen the arno 16 is cefrriedtothe right (Figure 6) a short distance., the seat 19 in the hub 18 ofthe arin 1G is disengaged from the cross pin 20 in the noch 1'? of theknob 14, and, at the seine tiine, ythe erin 1G is in'oved to the rightigure o) until it is clear of the detent the arm 16 sliding on the crossheed 33 of the orni 16. When the armi@ has been niojved to the right(Figure 6) until it is clear of the detent 411, the knob 27 mayberotated to swing the arm 16 counter clockwise (ligure 6), thereby toeffect a retracting of the locking bolt 34. i

The cross pin 20, carried by the knob lll, cooperating with the seat 1,9in the hub 1S of the erm 16, forros e connection between the knobs 27end 14:, by wey ot the sleeves 18 und so that the arm 16 may be swungcounter-clockwise, and the bolt 34 retracted,` troni either sideo'l thedoor, when the detent l1 is in the reised position shown in Figure 3 andis out oi: engagement with tliearin 16.

The projections 195 on thelatch 94C are beveled, und Adie latch muy be pushed to the lett (Figure8), the
